## Company history

Nessus, the vulnerability-scanning project that became the foundation of Tenable’s business, was introduced in 1998. Tenable’s founders were Ron Gula, Jack Huffard and Renaud Deraison. [12](https://app.finbar.com/go?id=P47916816)[36](https://www.tenable.com/blog/nessus-turns-20)[37](https://www.tenable.com/press-releases/tenable-founders-inducted-into-the-cyber-security-hall-of-fame) The predecessor company was incorporated in 2002; Tenable Holdings, Inc. was incorporated in 2015, and the predecessor was renamed Tenable, Inc. in 2017. [38](https://app.finbar.com/go?id=P12473353) In December 2016, Tenable named Amit Yoran chairman and CEO, effective January 2017. [39](https://www.tenable.com/press-releases/tenable-network-security-appoints-amit-yoran-as-chairman-and-chief-executive-officer)

In 2018, Tenable introduced Tenable.io Lumin, a cyber-exposure analytics product, and completed its initial public offering, with shares beginning to trade on Nasdaq under the ticker TENB. [40](https://www.tenable.com/press-releases/tenable-unveils-tenableio-lumin)[41](https://www.tenable.com/press-releases/tenable-announces-pricing-of-initial-public-offering)[42](https://ir.nasdaq.com/news-releases/news-release-details/nasdaq-welcomes-tenable-holdings-nasdaq-tenb-nasdaq-stock-market) From 2019 to 2021, acquisitions broadened its capabilities beyond traditional vulnerability management: Indegy added operational-technology security, and Alsid added identity security, alongside the launch of Tenable.ad.
